Use the Win32 function GetSystemTime() or the Delphi Time function before and afterwards then work out the number of milliseconds between the two.

To calculate the number of milliseconds do this (assuming you use the Delphi Time function):

var
 TimeAfter, TimeBefore : TDateTime;

.
TimeBefore := Time;
// Do your stuff here
TimeAfter := Time;

// How many milliseconds?
x := (TimeAfter - TimeBefore) * (86400 * 1000);  // 86400 seconds/day...


Cheers,

Raymond.

this is the statment to get millisecons from system time

var
  starttime,finishtime, actualresponse : TDateTime;
  Year, Month, Day, Hour, Min, Sec, MSec: Word;
begin
  starttime := Time;
  DecodeTime(starttime, Hour, Min, Sec, MSec);
  { display millisecons }
  label1.caption := inttostr(msec);

  Finishtime := Time;
  DecodeTime(finishtime, Hour, Min, Sec, MSec);
  { display millisecons }
  label2.caption := inttostr(msec);
 
{ you can also do this statment }
  actualresponse := finishtime - starttime;
  DecodeTime(actualresponse, Hour, Min, Sec, MSec);
  { display millisecons }
  label3.caption := inttostr(msec);

end;
